10 books cost $30. To figure it out, it's just 3 times the number of books. XD
Answer:
Step-by-step explanation:
N= 100+n(10)
An absolute value means something distance from 0, so |8| = 8 because the distance of 8 from 0 is 8. However the |-8| still equals 8 because the distance from -8 to 0 is 8
So with that in mind, we know that |-4| is 4 because the distance -4 is from 0 is 4
So we have 4*4 = 16
-5 is the answer
-11-(-6)= -5
